A report that vapor-phase pyrolysis of ammonia-borane (NH/sub 3/.BH/sub 3/) produces poly(aminoborane) has led to further examination of the solid pyrolysis reaction. An apparatus was designed with a pyrolysis tube attached to a commercial sublimer, which permitted collection of the desired product without contamination. A few torricelli of nitrogen pressure are maintained in the system to help initiate the decomposition, after which volatile materials are pumped over the cold finger held near -196/sup 0/C. The white solid condensate was warmed slowly to ambient temperature before isolation. From results of ir spectroscopy and x-ray powder diffraction, the new product is distinct from both the known and amorphous crystalline forms of poly(aminoborane). 2 tables.
